Tunable luminescent materials have attracted considerable interest for their wide applications in electronic optical devices, biological probes and sensors, tunable displays, and security technologies. Herein, we describe a strategy of coordination-driven self-assembly in order to prepare discrete tetraphenylethene-based platinum(II) bis-triangular dicycles 1 and 2 with aggregation-induced emission properties. The X-ray structure confirms that they possess two triangular cavities in which free rotation of the central TPE unit is restricted. As a kind of fluorescent material, the AIE-active dicycles have good emissions with wide tunability based on their aggregate states by changing different solvents, adjusting the temperature, or combining them with other dyes e.g., perylene via a co-assembly process.
